: 25 year old house with ABS plumbing...had wax replaced and sealed bottom of toilet on floor. Floor is dry and no leaks. Vent in roof is clean and functioning.

: Still has strong urine odor, even after cleaning, when used just once or twice.

: ???? -help pleaseHow long befor you changed the wax did the smell exist? It could if the floor was saturated for a while the wood has taken on this odor. You should also check that the water level in the bowl is not getting "siphoned" and allowing sewer smell to come in. My guess would be after checking to see if no leaks etc.it would likely be the wood has asorbed odor. Hardware store has odor eliminators. , or scrub wood area and spray with laundry bleach for a few days Good luck ..Hube
